Todd Lipcon commented on HBASE-3834:
------------------------------------
Sorry, not likely I have time to do this (HA taking up my time these days). I
don't have the logs handy, but it's easy to produce:
- Start HBase standalone with default configs (ie rootdir file:///tmp/hbase-foo)
- Insert some data, flush
- Shutdown hbase
- vim /tmp/hbase-foo/path/to/some/hfile. Randomly replace a few characters here
and there
- Start hbase
- Data gone :(
> Store ignores checksum errors when opening files

> Key: HBASE-3834
> URL: https://issues.apache.org/jira/browse/HBASE-3834
> Project: HBase
> Issue Type: Bug
> Components: regionserver
> Affects Versions: 0.90.2
> Reporter: Todd Lipcon
> Priority: Critical
> Fix For: 0.90.3
>
>
> If you corrupt one of the storefiles in a region (eg using vim to muck up
> some bytes), the region will still open, but that storefile will just be
> ignored with a log message. We should probably not do this in general -
> better to keep that region unassigned and force an admin to make a decision
> to remove the bad storefile.
